AP3595 (Obsolete)

Description

The AP3595 is a compact dual phase synchronous rectified buck controller specifically designed to deliver high quality output voltage. This device operates at adjustable operation frequency and is capable of delivering up to 60A output current. This controller integrates internal MOSFET drivers that support 12V+12V bootstrapped voltage for high efficiency power conversion. The bootstrap diode is built-in to simplify the circuit design and minimize external part count. The AP3595 features configurable gate driving voltage for maximum efficiency and optimal performance. The built-in bootstrap diode simplifies the circuit design and reduces external part count and PCB space. The output voltage is precisely regulated to the reference input that is dynamically adjustable by external voltage divider. Other features include adjustable soft start, adjustable operation frequency, and quick response to step-load transient. With afore-mentioned functions, the IC provides customers a compact, high efficiency, well-protected and cost-effective solution.
